Question

Explain 10 per cent law : In a grassland ecosystem if productivity of producers is 1000 tons/year then what will be the productivity of top carnivores ?

Answer 1

10% energy transfer law in the food chain is put forth by Lindeman. A pyramid of energy depicts the energy flow form one trophic level to another trophic level in the food chain. According to 10 percent law, 90% of the energy captured from the previous trophic level is lost as heat to the environment and only 10 percent is made available to the next trophic level. Energy flow is from environmental sunlight to producers, producers to primary consumers, primary consumers to secondary consumers and so on.
